LJJLh-le T (IE whom it may concern:

Be it known that l, OWEN DAVID Loose, e'suhjeet of the King of Great Britein, residingat 39 Victoria street, i festniiiister,

'llzondon; England, have invented new and useful Improvements in Gas-Producers, of which. the following is a specification.

This invention relates to improvements in gas producers, more especially those intended to be used with fuel containing high percentage of Water, such as pest.

According to this invention fuel, such as pest which may contain 70% or more of water, is introduced into at producer pro vided With an upward draft. The fuel is fed to the top of the reducer through a. long pipe lwhich may e provided with e rotsting'vqorm, or this pipe may be inclined end itself rotated. The pipe or the Worm terminates in a. hopper above the producer and is so arranged that the pest fuel drops into the producer through an air locked feeding device. The feeding device may itself be an extension of the Worm or tube, and rotating Withit. A pipe leading from the fuel feeding pipe at a. point neer the air locked feeding device connects the fuel feed ing pipe to the under side of the producer. In this pipe is a fan which drev-zs through the open end of the fuel feed pipe and delivers it to the producer hearth thus forming the air blast. I

The pipe forming the gas outlet from the produce surrounds the fneideegl pipe. In the case of a horizontal feed pipe provided with a worm this gas pipe is preferably not concentric with the feed .pipe but is ine at an angle so that its lower end is Ear from the producer, thus forming e t or in the case Where thefeed tube 1 inclined the gas pipe may he COHCSIIlJii-(J it and may be provided with tar traps prevent condensation products returning the produeer.

It will be seen that by these arrangements the hot gases from the producer impart to the fuel in the feed pipe'sonie of their best and part of the water in the fuel is evsporated and the steam thus formed mixesw the air sucked in by the fen, so that blast for the producer is mixed with the moisture obteined from the fuel. In order to regulate the amount of steam in air blast for varying contents otmoistnre in the fuel the blest pipe is provided with valve or system. of valves so arranged Ell n the pipe 2' e regulating valve 2' a and pass having e hearth Z) of fee wheel gearing w on a driven shalt g.

In combination with a gas producer for the use of fuels containing moistrre a feed pipe for the moist fuel, a pipe connected with the producer and surrounding the feed pipe for conveying hot gases from the producer to a space between the fuel feed pipe and said surrounding pipe and thus heating; it, means for drawing air through the fuel feed pipe and thus saturating the same with moisture during its passage through the fuel pipe, an air looked feeding device between the fuel pipe and'the producer, and a pipe for conveying moisture-laden air from the discharge and of the fuel feed pipe.

' 2. In combination with a gas producer, a fuel feed pipe, a feed worm in the fuel feed pipe, mains for rotating the feed worm, another pipe for conve 'ing the outgoing gases surrounding the. fue feed pipe, a scraper in the said pipe, means for rotating the scraper, means for drawing" air through the fuel feed pipe, and an air locked feeding device between the fuel feed pipe and the producer. 3. In combination Witha gas producer, a fuel feed pipe, afeed worm in the fuel feed pipe, means for rotating the feed worm, another pipe for conveying the outgoing gases surrounding the fuel feed pipe, a'scraper in the said pipe, means for'rotating the pipe, mains for drawing air through the fuel feed pipe, and an air locked feeding device be tween the fuel feed pipe and the producer.

4. in combination with a gas producer, a fuel feed pipe, a feed Worm in the fuel feed pipe, means for rotating the feed worm, an-

other pipe for conveying the outgoing gases surrounding the fuel feed pipe, a scraper in the said pipe, means for rotating the scraper, means for drawing air through the fuel feed pipe and leading it to the hearth of the producer, and an air locked feeding device between the fuel feed pipe and th producer.

5. In combination with a gas producer, a fuel feed pipe, a feed Worm in the fuel feed pipe, means for rotating the feed worm, another pipe for conveying the outgoing gases surrounding the fuel feed pipe, a scraper in the said pipe, means for rotating the pipe, means for drawing air-through the fuel feed pipe and leading it to the hearth of the producer, and an air locked feeding device between the fuel feed i e and the producer.
